PC DSR PLC

4.4.2 PGU connection (PORT # 0, PCD1 and PCD2) (RS 232) as communication
interface

When comissioning / programming are complete, the port can be used for other pur-

poses.

Option 1: Configuration with desired protocol

(S-Bus PGU configuration)

Option 2: Assignment (SASI) in the user program

(the port must not be configured as an S-Bus PGU port)

■ If another programming device is connected during operation

instead of the peripheral device, the unit will switch over

automatically to PGU mode (pin 6 logical “1” (DSR); in PGU

mode: DSR PING = “1”).

■ Before using the port to connect another peripheral device,

Port #0 must be reconfigured by means of an SASI instruction.

1) When communicating with terminals, check whether some connections are pro-

vided with bridges or need to be set to “H” or “L” with the “SOCL” instruction. It is

generally recommended to use a handshake (RTS / CTS)
